The **8502SCO2V03S** is a specific model of a NEMA-rated magnetic contactor manufactured by Square D (Schneider Electric). It is primarily used for controlling electric motors or heavy inductive loads. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. General Specifications The model number reveals specific characteristics about the device's build and capacity: | Component | Description | | :--- | :--- | | **Product Type** | NEMA Magnetic Contactor | | **NEMA Size** | Size 1 (Rated for higher current than Size 0) | | **Ampere Rating** | 27 Amps | | **Pole Configuration** | 3-Pole (3-Phase) | | **Enclosure Type** | Open (No outer metal box, intended for panel mounting) | --- ### 2. Key Electronic Components #### A. The Coil (V03 Suffix) The suffix **V03** indicates the specific control voltage required to energize the contactor. * **Voltage:** 220V AC @ 50 Hz / 240V AC @ 60 Hz. * **Function:** When this voltage is applied to the coil terminals, it creates a magnetic field that pulls the power contacts closed. #### B. Separate Control Circuit (S Suffix) The **S** suffix is critical for the wiring configuration: * **Feature:** Separate Control. * **Explanation:** This means the control circuit (the coil) is electronically isolated from the main power lines. This allows you to run the motor at a high voltage (e.g., 480V) while controlling the switching with a lower or separate voltage source (240V). #### C. Power Contacts * **Material:** Usually silver-cadmium oxide alloy to resist welding and arcing. * **Voltage Rating:** Rated for up to 600V AC. --- ### 3. Motor Horsepower (HP) Ratings The electronic capacity of the 8502SCO2V03S varies based on the operational voltage: | Voltage | Phase | Max Horsepower (HP) | | :--- | :--- | :--- | | 200V AC | 3-Phase | 7.5 HP | | 230V AC | 3-Phase | 7.5 HP | | 460V AC | 3-Phase | 10 HP | | 575V AC | 3-Phase | 10 HP | --- ### 4.
